Has Ronaldo ever won the World Cup?

Has Ronaldo ever won the World Cup?

It's important to clarify which Ronaldo you're referring to, as both Cristiano Ronaldo and Ronaldo Nazário (also known as Ronaldo or R9) have been prominent figures in football:

• Cristiano Ronaldo: No, Cristiano Ronaldo has not yet won the FIFA World Cup with the Portugal national football team. He has come close, reaching the semifinals in 2006 and the quarterfinals in 2018 and 2022, but unfortunately hasn't lifted the trophy.
• Ronaldo Nazário: Yes, Ronaldo Nazário did win the World Cup twice with Brazil. He was part of the squad that triumphed in 1994 (though he didn't play due to injury) and played a starring role in their 2002 victory, scoring both goals in the final against Germany and earning the Golden Boot with eight goals throughout the tournament.

Therefore, depending on which Ronaldo you meant, the answer to whether they've won the World Cup is either no (Cristiano Ronaldo) or yes (Ronaldo Nazário).

I hope this clarifies the information!
